Description
Technical Field
The invention relates to the technical field of data distribution, in particular to a method and a system for multi-process distribution of recording data based on Android equipment.
Background
Due to strict management of Google (Google) corporation on recording permission, an Android system (Android system) defaults to a single recording form, and does not support simultaneous acquisition of recording data by multiple applications and multiple processes, but a vehicle-mounted service has a requirement of sharing the recording data among the multiple applications or the multiple processes.
At present, the mainstream mobile phone Android operating system takes a millet mobile phone (MIUI) and an EMUI mobile phone (EMUI) as examples, and records data are shared among multiple applications or multiple processes by rewriting Android underlying recording source codes and managing through recording priorities. But the requirement on the bottom layer modifier is high, and other problems are easy to occur due to the need of relating to the Android bottom layer related source codes. Furthermore, since the modification scheme is not generic, but needs to be adapted for different codecs, it is also easy to create compatibility problems, and partial source code adjustments still need to be made at different devices. However, the current vehicle-mounted systems are not relatively compatible, most of the systems are divided into time slices, and only one process is allowed to record in the same time slice, and recording data cannot be shared among multiple applications or multiple processes. Therefore, the problem of sharing the recording data among multiple applications or multiple processes of the vehicle-mounted system is an urgent need in the industry.

Another objective of the present invention is to provide a transmission policy selection scheme, which is implemented by determining the current device operating mode and communication relationship, and intelligently selecting a specific transmission mode, so that only recording parameters are transmitted in the application layer, and corresponding recording data can be obtained, thereby avoiding a complex implementation mode of multi-process recording, significantly improving the distribution efficiency of inter-application and inter-process recording data, reducing the encapsulation difficulty of the upper layer of the application, saving device performance and memory occupancy rate, and meeting various service requirements.
Therefore, according to one aspect of the invention, a multiprocess distribution method based on recording data of Android equipment is provided, which comprises the following steps: before the current application terminal obtains the recording data, determining a data source based on the response condition of a designated communication message sent by the current application terminal, wherein the data source is an Android system or other application terminals serving as a server terminal; and the current application end acquires the recording data according to the determined data source. Firstly, a data source of the recording data is released from dependence on an Android system, so that an application end can also be used as the data source, and the problem of distribution of the recording data among multiple processes and multiple applications can be solved from an application layer. Then, the inventor also conceives that the data source is determined by the application terminal in a message interactive response mode before the recording data is obtained, so that the current application terminal can obtain the recording data from the system and other application terminals serving as the server terminal, thereby realizing the distribution of the recording data of the application layer, avoiding various defects of realizing the distribution of the recording data among multiple applications and multiple processes by modifying bottom codes, avoiding excessive operation on the application layer and avoiding the complex realization of the multi-process recording.
In some embodiments, the determining of the data source based on the response of the specified communication message sent by the current application before the recorded sound data is obtained by the current application comprises
The current application terminal is configured to respond to the starting instruction, acquire all application terminals on the Android equipment and send specified communication messages to all the application terminals;
the current application terminal determines a data source based on the received response message to the specified communication message, and the data source is realized as follows: and when the response message is received, determining the sender of the response message as a data source, or when no response message is received, taking the Android system as the data source, setting the Android system as a server and configuring the Android system as a server to return the response message when specified communication messages of other application terminals serving as clients are received. When a current application end needing to use the recording data is started, communication message interaction is carried out on all the application ends to determine whether the known application uses the recording data, when the existing application end is determined to use the recording data, the application end is used as a server end providing a data source according to response information to obtain the recording data from the server end, and when only the recording data is determined to be used by the application end, a mode of obtaining the recording data from an android system is adopted, the recording data is effectively shared among multiple processes and multiple applications, the whole implementation process does not make framework change on a system bottom layer, and the implementation mode is simple.
In some embodiments, when the current application terminal acquires the recording data according to the determined data source and the data source is an Android system, the recording data is directly acquired from the Android system; and when the data source is other application terminals serving as the server terminal, creating a transmission channel according to the instance information of the other application terminals, and acquiring the recording data through the created transmission channel. For the condition that the data source is an Android system, the recording data are directly obtained in an original mode, and for the condition that the data source is other application ends, the data can be directly transmitted through the created transmission channel, so that the distribution efficiency of the recording data between applications and processes is remarkably improved, and the application upper layer packaging difficulty is reduced. And the data source can be determined based on the instance information of other application terminals, namely the working mode and communication relation of the current equipment, and a specific transmission mode can be intelligently selected, so that all recording modes can be effectively compatible and the transmission efficiency can be improved.

The specific information of the current transmission object can be positioned according to the specific content of the example information, so that a proper transmission strategy can be determined, namely a proper transmission mode is selected, and the transmission of the recorded data is directly carried out through the set transmission channel and the set transmission mode, so that the transmission mode can be selected intelligently, the distribution transmission efficiency is improved, and the compatibility is improved.
In some embodiments, the determination of the selected transmission mode according to the process number of the application end or the communication port of the application end is realized by judging according to the process number of the application end, when other application ends and the application end are judged to be in the same process, AIDL is selected as the transmission mode, otherwise, socket is selected as the transmission mode; or judging according to the communication port of the application end, when judging that other application ends and the application end are positioned in the same network segment, selecting AIDL as a transmission mode, and otherwise selecting Socket as the transmission mode. Therefore, by adopting the mode of combining AIDL and Socket in the transmission layer, the working mode and the communication relation of the current equipment can be judged, the specific transmission mode is intelligently selected, and the complex realization of multi-process recording is avoided. For data interaction between the same processes, real-time synchronous transmission of the recorded data can be realized only by using one transmission medium, and for data interaction between different processes or different devices, AIDL is selected as an internal transmission mode, and Socket is selected as a transmission mode between the processes or the devices, so that the application upper-layer encapsulation difficulty can be effectively reduced, and the distribution efficiency is improved.
In some embodiments, the current application further performs the following processing before determining the data source: in response to a starting instruction, before all application terminals on the Android device are acquired, an Android recording interface is started to initialize recording configuration; when the recording data is obtained according to the determined data source, the current application end also transmits the configured initialization information to the data source so as to obtain the recording data. Therefore, the application end only needs to set the required recording parameters according to the requirements, the required recording data can be obtained by introducing the recording parameters, and the complex realization of multi-process recording can be effectively avoided.

Therefore, the data source type can be accurately positioned through the data source determining module to determine that the recording data is acquired from the Android system or other application terminals serving as the server side, and then the recording data is acquired from the corresponding data source based on the data acquiring module, so that the problems that the recording data is easily generated when all applications or processes can simultaneously acquire the recording data from the system by modifying the bottom layer codes of the system are avoided, the recording data sharing among multiple applications and multiple processes can be realized only by performing simple operation from the application layer, and the complicated realization of multi-process recording is avoided because excessive operation is not required at the application layer.

The data source is determined by the message distribution unit and the message response unit, the transmission object can be further refined, so that the recording data can be directly acquired at the application layer, the application end which uses the recording data of the system for the first time is configured into the server end which distributes the subsequent recording data by the server end configuration unit, and other application ends can also be used as the data source, so that the aim of distributing the recording data among multiple processes and multiple applications at the application layer is fulfilled, excessive operation is not needed by the method, and the complex realization of multi-process recording is avoided.

The method for multi-process distribution of the recording data based on the Android device can be applied to terminal devices which need to perform multi-process and share the recording data among multiple applications, such as a car machine, a computer, a smart phone, a tablet computer, a smart home and other terminal devices which have recording functions and voice interaction requirements, and the method is not limited to this. The scheme of the invention can realize the sharing of the recording data in the application layer, so the bottom layer code does not need to be modified, and the sharing of the recording data among multiple applications and multiple processes can be quickly, simply and efficiently realized on the equipment applying the Andriod system.
Fig. 1 schematically shows a flowchart of a recording data multi-process distribution method based on an Android device according to an embodiment of the present invention, and as shown in fig. 1, this embodiment includes the following steps:
step S101: and the application terminal determines the data source before acquiring the recording data. The data source in this embodiment is an Android system or another application terminal serving as a server terminal. Taking an Android vehicle-mounted system as an example, in practical application, a situation that a plurality of applications or different processes need to use recording data at the same time may exist, for example, when a bluetooth call is made, a user may want to start voice navigation at the same time, and at this time, a situation that different applications need to use recording data at the same time is generated; for another example, in a vehicle-mounted system loaded with a voice assistant, there may be a situation where the recognition module and the wake-up module need to obtain the recorded data at the same time, and in a general situation, the recognition module and the wake-up module are independent and parallel, and at this time, a situation where the recorded data needs to be used at the same time between different processes occurs. In the embodiment of the present invention, the current application end is, for example, an identification module, a wake-up module, a bluetooth application, a navigation application, or a music application, which is currently started and needs to use the recorded data. When a user starts a current application end, according to the technical implementation of the embodiment of the invention, the current application end firstly acquires all application ends on the Android device and sends specified communication messages to all the application ends to determine data sources, and then the current application end determines the data sources based on the received response messages to the specified communication messages. The sent specified communication message is a broadcast message encapsulated according to a custom protocol and used for determining whether other application terminals are already using the recorded data, when the other application terminals receive the message, the specified communication message is parsed according to the custom protocol, and a response is made according to the self condition, specifically, if the other application terminals are already using the recorded data and are configured as a service terminal, the other application terminals serving as the service terminal respond to the specified communication message, namely, feedback response messages, according to the custom protocol. In this way, the current application terminal may determine the data source according to the response to the specified communication message received by the current application terminal, specifically, when receiving the response message, the current application terminal determines the sender of the response message as the data source, and if not receiving any response message, the current application terminal uses the Android system as the data source. Preferably, when the determined data source is the Android system, the current application end sets itself as the server end, and configures the application end to return a response message when receiving the specified communication message, so that if one application end is an application using the recording data for the first time, the application end is used as a data source for distributing the recording data, so that other applications can not obtain the recording data from the system any more, but can obtain the recording data from the application end, and thus, the recording data distribution and sharing of the application layer are realized. The specific implementation manner of setting the self as the server is to create the server first, then set the communication port, issue server information to the outside (other applications), and store the communication port information, illustratively, the server can be created on the self through aid id l, and the server information is distributed and stored, so that other applications can access and acquire data as clients.
Step S102: and the application end acquires the recording data according to the determined data source. After the data source is determined, when the data source is an Android system, the recording data is directly obtained from the Android system, and the obtaining mode is realized by directly obtaining the recording data from a recording inlet of the Android system, and the recording data can be obtained by adopting an original recording data obtaining mode. And when the data source is other application terminals serving as the server terminal, creating a transmission channel according to the instance information of the other application terminals, and acquiring the recording data through the created transmission channel. In a specific implementation, when a current application end sends a specified communication message, other application ends making a response can obtain the self-instance information through the corresponding interfaces of the Android system and package the self-instance information into a response message according to a custom protocol so as to send the response message to the current application end making a request, so that the current application end can create a transmission channel according to the instance information of the other application ends, specifically, the transmission channel can be implemented by determining a selected transmission mode according to the process number of the application end or the communication port of the application end, exemplarily, the judgment can be carried out according to the process number of the application end, when the other application ends and the application end are judged to be in the same process, AIDL is selected as the transmission mode, otherwise, socket is selected as the transmission mode; or judging according to the communication port of the application end, when judging that other application ends and the application end are positioned in the same network segment, selecting AIDL as a transmission mode, and otherwise, selecting Socket as the transmission mode. And establishing communication connection with the application end communication port through the instance information according to the selected transmission mode. Through the combination of the socket and the AIDL, the distribution efficiency of the recording data between applications and processes is obviously improved, and the difficulty in upper-layer packaging of the applications is reduced.
For example, in a voice application of a vehicle system, the recognition module (ASR) and the wake up module (WAKEUP) are generally independent and parallel. After the method based on the embodiment is adopted, when the identification module is taken as a main process, the main process defaults to start recording, sets the main process as a server and prepares to distribute data outwards, at the moment, if the process of the wake-up module is started, the existing main process data, namely the recorded data used by the identification module, is detected by sending a specified communication message and acquiring a response message, then the recorded data can be acquired only through a distribution channel, namely the establishment transmission mode, and the strategies such as data congestion and data caching do not need to be additionally processed, so that the code reusability is improved, and the coupling relation between modules is reduced.
Taking the bluetooth application of the vehicle-mounted system as an example, when a bluetooth call is made, a common method is to stop other recordings and use the bluetooth application exclusively, but at this time, if there is a vehicle-mounted navigation request, and the user is handling the driving scene, it is not convenient to operate with hands. After the method is based on the embodiment, after a Bluetooth call is received, the communication is carried out with all applications on the vehicle owner device to determine a data source, if no other application end uses recording data, the Bluetooth call acquires the recording data from the vehicle-mounted system, meanwhile, the application of the Bluetooth call is set as a server, at this time, if a vehicle-mounted navigation request is started, the application end of the Bluetooth call is determined to be the data source by sending a specified communication message and an acquisition response message, so that the communication is established with the application end, when the communication is established, a data channel is confirmed to be a cross-process through instance information in the response message, the recording data is acquired in a corresponding transmission mode, exclusive processing is not needed, and cross-process sharing of the recording data is achieved.
In a preferred embodiment, the current application further performs the following processing before determining the data source: firstly, responding to a starting instruction of the whole distribution method, starting an Andriod recording interface, and initializing recording configuration, wherein the initialization comprises setting parameters such as recording sampling rate, bit data, buffer area preparation and the like. When the recording data are obtained according to the determined data source, the current application end also transmits the configured initialization information to the data source so as to obtain the recording data. Therefore, the current application end can acquire the required recording data from other application ends or systems only by setting the required recording parameters without performing other processing, and the complex realization of multi-process recording data distribution is avoided.
According to the method provided by the embodiment, the recording data can be intelligently selected to be shared and distributed in a specific transmission mode under the condition of multi-process operation, excessive operation is not required to be performed in an application layer, and the complex realization of multi-process recording is avoided.

In this way, the current application terminal may determine the data source according to the response to the specified communication message received by the current application terminal, specifically, when receiving the response message, the current application terminal determines the sender of the response message as the data source, and if not receiving any response message, the current application terminal uses the Android system as the data source.

And establishing communication connection with the communication port of the application end through the instance information according to the selected transmission mode. For further concrete implementation, reference may be made to the above method portion, which is not described herein again.
